English is indeed an agglomeration of languages, and I believe that is enriching. What I object to in crosswords is the use of non-English words that are not used by speakers of the language (in this I am in the minority). Tushie is not an English term and not used by the Goyim. Similarly, comare /kumad/ is used only by those of Italian descent, and, therefore, is not grist for the crossword mill. There is, of course, a gray area as word usage evolves. Nosh may be used by more than Jews, at least in L.A. and N.Y. where The Bagel Nosh was an eatery franchise.
